What to check on a Mercedes-Benz B-Class with this engine

  • On a diesel, check the particulate filter (DPF), the injectors and the dual-mass flywheel: they are the expensive repairs.
  • Test the clutch or the automatic transmission from a cold start and in the low gears.
  • Compare the odometer with the readings in the service records and in the VIN history report: a big gap means the mileage was rolled back.
